Abstract

The ring-like pattern of late gadolinium enhancement (RL-LGE) on cardiac magnetic resonance (CMR) has been proposed as a distinctive imaging marker of arrhythmogenic cardiomyopathy (ACM) with left ventricular (LV) involvement. However, the clinical characteristics and prognostic significance remain to be further clarified.
